About this part

Product Details

When you're rebuilding the top end of your Dodge Viper V-10, you want parts that can handle the stress. This set includes ten Manley Race Master exhaust valves, each measuring 1.580 inches in diameter. These aren't just any valves; they're built for engines that see serious use, especially those running up to 8000 RPM.

Manley uses high-quality stainless steel for these exhaust valves, which is crucial for resisting the heat and pressure inside the combustion chamber. The stems are chrome-plated and feature hard tips, adding to their lifespan and wear resistance. You'll also notice the swirl-polished under-head areas and fully machined faces, designed to help air flow more smoothly and improve how efficiently the engine burns fuel. These are also a recommended choice for exhaust valves in engines running on alcohol fuel.

This set is specifically for the exhaust side, and you get ten valves, which is what you'd typically need for a V-10 engine. If you're aiming for reliable performance under demanding conditions, these valves are a solid option.
